Drive Belt Tightener

This belt tensioning device provides a convenient and accurate adjustment to prevent bearing overloading, a belt overstress and excessive loading of drive motors.

Plate 1, which is mounted to a backplate, not shown, by screws 2 and 3, pivots around point 4. Arm assembly 5, which also pivots around point 4, is spring loaded against stud 7 on plate 1. Pulley assembly 8, which carries belt 9, is mounted on plate 1. Pulleys 10 and 11 are fixed members of the belt transport.

Arm assembly 5 is moved in a counterclockwise direction, rotating the complete unit until slack is removed from belt 9. When slack has been removed, arm 5 will leave stud 7 initiating tension on belt 9 by action of spring 6. Continued rotation of arm 5 increases tension on belt 9.

When indicator edge 12 or arm 5 is aligned with a proper mark 13 on graduated scale of plate 1, the proper tension is set on belt 9. Plate 1 is then locked against the backplate by screw 3. Arm 5 resets back to stud 7 by the action of spring 6. Arm 5 is locked by screw 2.
